Challenge - 5 Problems

❓ Predict Output

What is the output of isDisplayed() for a hidden element?

Consider a Selenium WebDriver test where the following code is executed:

WebElement hiddenElement = driver.findElement(By.id("hiddenDiv"));
boolean visible = hiddenElement.isDisplayed();
System.out.println(visible);

The element with id "hiddenDiv" exists in the DOM but has CSS style display:none;. What will be printed?

Selenium Java

WebElement hiddenElement = driver.findElement(By.id("hiddenDiv"));
boolean visible = hiddenElement.isDisplayed();
System.out.println(visible);

A false

B true

C NoSuchElementException

D StaleElementReferenceException

💡 Hint

An element with display:none is present but not visible on the page.

The isDisplayed() method returns false if the element is hidden via CSS like display:none, even if it exists in the DOM.

❓ assertion

Which assertion correctly verifies a button is enabled?

You want to write a JUnit assertion to check that a button with id "submitBtn" is enabled before clicking it. Which assertion is correct?

Selenium Java

WebElement submitBtn = driver.findElement(By.id("submitBtn"));

A assertFalse(submitBtn.isSelected());

B assertTrue(submitBtn.isEnabled());

C assertFalse(submitBtn.isEnabled());

D assertTrue(submitBtn.isDisplayed());

💡 Hint

Enabled means the element can be interacted with.

The isEnabled() method returns true if the element is enabled and can be clicked or typed into. The assertion should check for true.

Why does isSelected() return false for a checked checkbox?

Given the code:

WebElement checkbox = driver.findElement(By.id("agreeTerms"));
boolean selected = checkbox.isSelected();
System.out.println(selected);

The checkbox is visibly checked on the page, but the output is false. What is the most likely cause?

Selenium Java

WebElement checkbox = driver.findElement(By.id("agreeTerms"));
boolean selected = checkbox.isSelected();
System.out.println(selected);

A The locator finds a different element, not the checkbox input

B The checkbox is disabled, so isSelected() returns false

C isSelected() only works for radio buttons, not checkboxes

D The checkbox is inside an iframe and not switched to it

💡 Hint

Check if the element found is the actual input element representing the checkbox.

If the locator finds a label or container instead of the input element, isSelected() will return false even if the checkbox is checked.

Which Selenium method checks if a radio button is selected?

You want to verify if a radio button is selected in your test. Which method should you use?

A isDisplayed()

B isVisible()

C isSelected()

D isEnabled()

💡 Hint

Think about the state that indicates selection for inputs like radio buttons and checkboxes.

The isSelected() method returns true if a radio button or checkbox is selected.

How to wait until a button is enabled before clicking in Selenium Java?

You want to wait up to 10 seconds until a button with id "saveBtn" becomes enabled before clicking it. Which code snippet correctly implements this using WebDriverWait?

A Thread.sleep(10000); driver.findElement(By.id("saveBtn")).click();

B new WebDriverWait(driver, Duration.ofSeconds(10)).until(driver -> driver.findElement(By.id("saveBtn")).isDisplayed()); driver.findElement(By.id("saveBtn")).click();

C new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.visibilityOfElementLocated(By.id("saveBtn"))); driver.findElement(By.id("saveBtn")).click();

D new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.id("saveBtn"))); driver.findElement(By.id("saveBtn")).click();

💡 Hint

Look for a condition that waits for the element to be clickable (visible and enabled).

ExpectedConditions.elementToBeClickable waits until the element is visible and enabled, so it can be clicked safely.
